All eight SPI ports share the same SCK, MOSI, and MISO pins, so users may enable only one port at any given time. Once you have added either the PS based or axi based SPI interface to your Zynq design and exported it to the SDK (Software Developement Kit) you can open the system. I did two arguably dumb things that kept my SPI experience from being smooth sailing. 10) March 31, 2017 Notice of Disclaimer The information disclosed to you hereunder (the “Materials”) is provided solely for the selection and use of Xilinx products. My question is can I use this JTAG to program/test other FPGA brands as well (Altera Cyclone 2 for example) ? Typically, the SPI Master that the user is commanding, has a Transmit Buffer, which sends bytes out on the MOSI line of the SPI bus and a Receive Buffer, which receives bytes in from the MISO line of the SPI bus. In this example, the value of 7 ns represents the SPI flash operating with a load of 30 Jun 19, 2017 I believe when you add the axi quad spi to your block design you can right click on it and run an xilinx made IP example to see how it is used. 3 has issues with SPI access on Spartan 6 devices, Xilinx 12.
